   Use
            -stack option to change the default size.
相关文件如下：
;这是程序，用C的写的
#include"math.h"
#pragma DATA_SECTION(data1,"data_buf1")
float data1;
#pragma DATA_SECTION(data2,"data_buf2")
float data2;
#pragma DATA_SECTION(data3,"data_buf3")
float data3;
#pragma DATA_SECTION(data4,"data_buf4")
float data4;
#pragma DATA_SECTION(data5,"data_buf5")
float data5;
void main(void)
{
  data1=12.7;
  data2=9.2;
  data3=data1*data2;
  data4=data1/data2;
  data5=sqrt(12.7);
  }
；这是中断向量程序
